hyperspy._components.rc module

class hyperspy._components.rc.RC(Vmax=1.0, V0=0.0, tau=1.0, module='numexpr', **kwargs)

Bases: Expression

RC function component (based on the time-domain capacitor voltage response of an RC-circuit)

\[f(x) = V_\mathrm{0} + V_\mathrm{max} \left[1 - \mathrm{exp}\left( -\frac{x}{\tau}\right)\right]\]

Variable

Parameter

\(V_\mathrm{max}\)

Vmax

\(V_\mathrm{0}\)

V0

\(\tau\)

tau
Parameters:

  • Vmax (float) – maximum voltage, asymptote of the function for \(\mathrm{lim}_{x\to\infty}\)

  • V0 (float) – vertical offset

  • tau (float) – tau=RC is the RC circuit time constant (voltage rise time)

  • **kwargs – Extra keyword arguments are passed to the Expression component.
